## 🎨 Terrain System Details

### Terrain Notation Format
```
terrain="TopLeft,TopRight,BottomLeft,BottomRight"
```

### Standard 3×3 Pattern (9 basic tiles)
```
[TL ,,,0]  [T  ,,0,0]  [TR ,,0,]
[L  ,0,,0] [C  0,0,0,0] [R  0,,,0]
[BL ,0,,]  [B  0,0,,]   [BR 0,,,]
```

### Inner Corners (4 advanced tiles)
```
Inner-TL: 0,,0,0
Inner-TR: 0,0,0,
Inner-BL: ,0,0,0
Inner-BR: 0,0,,0
```

---

## 🔧 Wang Sets (Fence System)

### Edge-Based Notation
```xml
<wangtile tileid="X" wangid="T,T,R,R,B,B,L,L"/>
```

**Values:** 0 = no edge, 1 = edge exists

### Fence Layout
```
Row 1: Horizontal pieces (left end, mid, right end)
Row 2: Vertical pieces (top end, mid, bottom end)
Row 3: Corners (TL, TR, BL, BR)
Row 4: Junctions (T-cross, 4-way) + Gates
```

## 🚀 Implementation Workflow

### Phase 1: Setup (Completed ✅)
- [x] Create TSX tileset files
- [x] Define terrain sets
- [x] Define Wang sets
- [x] Write documentation
- [x] Create visual references

### Phase 2: Testing (Next Step ⬜)
- [ ] Open micro_farm_8x8.tmx in Tiled
- [ ] Import .tsx tilesets
- [ ] Test Terrain Brush with Grass terrain
- [ ] Test TilledSoil terrain
- [ ] Test Wang Brush with Fences
- [ ] Export to JSON
- [ ] Verify in Phaser

### Phase 3: Integration (Future ⬜)

❌ Seams and mismatched edges  
❌ Tedious corner selection  
❌ Inconsistent results  
❌ Time-consuming iteration  

### After Auto-Tiling:
✅ One-click terrain painting  
✅ Perfect edge transitions  
✅ Automatic corner detection  
✅ Consistent, professional look  
✅ 10x faster map creation

### Functional Testing
- [ ] Terrain Brush (T) works
- [ ] Wang Brush works
- [ ] Erase Tool (E) removes terrain
- [ ] Fill Tool (Shift+T) fills large areas
- [ ] JSON export contains correct tile IDs
- [ ] Phaser loads and renders map correctly

### Performance
- [ ] Map loads quickly in Tiled
- [ ] Export to JSON is fast (<5s)
- [ ] No lag when painting terrain
- [ ] File size is reasonable (<500KB for 8×8 map)

## 🆘 Common Issues & Solutions

### Issue 1: Terrain Tab Missing
**Cause:** PNG loaded instead of TSX  
**Fix:** Import External Tileset, choose `.tsx` file

### Issue 2: Wrong Tiles Selected
**Cause:** Tile IDs don't match PNG layout  
**Fix:** Edit `.tsx` file, adjust `<tile id="X">` numbers

### Issue 3: Wang Set Not Visible
**Cause:** Tiled version too old  
**Fix:** Update to Tiled 1.10+

### Issue 4: Terrain Brush Doesn't Work
**Cause:** Using Stamp Brush (B) instead of Terrain Brush (T)  
**Fix:** Press `T` key, select terrain from Terrains panel

2. Create additional terrains (stone, snow, lava)
3. Document any issues or improvements needed
4. Update Knowledge Base with learnings

### Long-term (This Month)
1. Expand to larger world maps (100×100+)
2. Create template maps with pre-configured terrains
3. Add animated terrain tiles
4. Integrate with procedural generation system

---

## 💡 Pro Tips

1. **Start Small:** Test on 8×8 map first, then scale up
2. **Layer Order Matters:** Ground → Paths → Soil → Fences → Decorations
3. **Save Often:** Ctrl+S after each major change
4. **Use Shortcuts:** `T` (Terrain), `B` (Stamp), `E` (Erase), `Shift+T` (Fill)
5. **Test Exports:** Always verify JSON in Phaser before committing
6. **Mix Manual + Auto:** Use auto-tiling for base, add manual variations
